During this experiment we examined how catalyst break down hydrogen peroxide. At first we experimented on how catalyst affects H2O2 normally. Then how it breaks H2O2 in different time intervals. We discovered that after boiling the catalyst it denatures and can no longer function. Having accidentally boiled the catalyst in a plastic test tube, we had to redo those lab procedures. Beyond that the lab went smoothly, besides the ever-so-likely chance that we measured something inaccurately from human error.
